Circuit Documentation
Summary
This circuit is designed to convert mechanical energy into electrical energy using a hand-crank handle connected to a DC motor. The generated AC voltage is then rectified using a bridge rectifier and regulated to a stable 5V DC output using a 7805 voltage regulator. The circuit also includes an electrolytic capacitor for smoothing the output, a resistor and LED for indication, and a USB female connector for providing a 5V output.
